- Brief Summary
The aim of this project is to evaluate the safety and acceptability of our online, home-based, personalized, neuro-technological mindfulness-based intervention in entraining anxiety regulation and ameliorating anxiety in healthy adults. Our technology will deliver a mindfulness-based anxiety regulation intervention through a neuro-/ bio-feedback-based game interface that is driven by an electroencephalography (EEG) algorithm. We hypothesize that the intervention would be safe and acceptable. In exploratory analyses, we further hypothesize that the intervention would help entrain anxiety regulation and ameliorate anxiety in healthy adults. Data will be analyzed quantitatively and qualitatively to inform development of our intervention and future research studies.
- Detailed Description
Anxiety disorders, defined by excess worry, hyperarousal and fear, are amongst the most common class of psychiatric conditions in adults. Large population-based studies on anxiety disorders estimated a lifetime prevalence of 33.7% and a 12-month prevalence between 2.4% and 29.8%. In Singapore, however, studies have only established the prevalence of a limited range or anxiety disorders. In a nationwide, cross-sectional, epidemiological survey, the lifetime prevalence of anxiety disorders, specifically Generalized Anxiety Disorder and Obsessive-Compulsive Disorder, rose from 0.9% and 3.0% respectively in 2010, to 1.6% and 3.6% in 2016. If untreated, anxiety disorders could result in a range of personal and societal costs, such as interpersonal dysfunctions, employment, physical health, social functioning, and frequent primary and acute care visits, resulting in a poor quality of life.
A large proportion of the population experiences subclinical symptoms of anxiety disorders which impede daily functioning and well-being, but most often do not seek professional help or fall below the radar of psychiatric services. Current treatment guidelines recommend pharmacotherapy (i.e. selective serotonin reuptake inhibitors \[SSRIs\] or venlafaxine) and psychotherapy (i.e. cognitive behavior therapy \[CBT\]) as first-line treatments for anxiety disorders. Unfortunately, SSRIs are associated with an increased risk of suicide in young adults. Thus, local practices often incorporate more psychological therapies in the treatment of anxiety disorders. However, CBT is labor-intensive and time-consuming - which is incompatible with the demanding lifestyle Singaporeans lead these days. Moreover, therapeutic outcomes are also very much therapist dependent. Due to the fear of stigma that is particularly salient in the local context, individuals with anxiety may be deterred from engaging with therapists. Even if these individuals do receive adequate treatment, existing literature shows that outcomes for recommended treatment modalities are sub-optimal at best, i.e. overall mean remission rate of CBT is 51% while pharmacotherapy is significantly lower. With the low rates of help-seeking behaviors and dismal success rates of existing therapies, novel interventions for anxiety are apposite and vital.
The benefits of mindfulness-based interventions have been extensively researched in anxiety disorders in recent years. Improvements reported across a range of outcomes include enhanced ability to cope with stress, reduced depressive and anxiety symptom severity, as well as improved sleep quality, all of which lead to increased life satisfaction and overall well-being. Not all anxiety regulation strategies are helpful, and mindful emotion regulation presents one promising strategy by cultivating a changing of relationship with one's emotions. Specifically, this strategy facilitates reduced reactivity to emotional stimuli by encouraging one to meet, accept, and detach from one's aversive feelings, thoughts, and ineffective habitual responses. Unfortunately, clinically anxious individuals with no experience in such practices could find it challenging to engage in them as they often require a high degree of individual discipline. Coupled with the fact that sustained practice is crucial to yield the benefits of mindfulness practice, an appealing mode of treatment delivery is necessary. To this end, gamification strategies could be useful: gamification strategies have been shown useful in motivating health-related behaviors through interaction with the immersive interventional programs. Recent preliminary studies have also suggested that neuro-/ biofeedback-based relaxation and mindfulness training is useful for both healthy and anxious individuals.
Accordingly, we have developed an online, home-based, personalized, neuro-technological mindfulness-based intervention and seek to conduct a preliminary study with healthy young adults to evaluate its safety and acceptability. Our technology will deliver a mindfulness-based anxiety regulation intervention through a neuro-/ bio-feedback-based game interface that is driven by an electroencephalography (EEG) algorithm. We hypothesize that the intervention would be safe and acceptable. We further hypothesize that the intervention would help entrain anxiety regulation and ameliorate anxiety in healthy adults.

Group Intervention Description Intervention Brain-Computer Interface Participants will undergo a brief interactive psychoeducation session four times a week for two weeks. For each session, participants will wear a commercially available Electroencephalography (EEG) headset and play a downloaded online game for a total of 30 minutes. Participants can feel free to play the game for more than the instructed frequency during their 2-week intervention participation.
- Primary Outcome Measures
Name Time Method Number of Adverse Events/Serious Adverse Events Reported Throughout the intervention period (2 weeks), which are weeks 5 and 6 for the waitlist control group. The total number and severity rating of all adverse events reported will be collated at the end of the study.
Beck Anxiety Inventory II (BAI-II) Intervention group: Changes from baseline anxiety symptoms (week 1) to post-intervention (week 4) and follow-up (week 7). Waitlist control group: Changes from baseline anxiety symptoms (week 1) to pre-intervention (week 4) and post-intervention (week 7). 21-item questionnaire being scored on a scale value of 0 (not at all) to 3 (severely). Higher total scores indicate more severe anxiety symptoms.
State-trait Anxiety Inventory (STAI) Intervention group: Changes from baseline anxiety symptoms (week 1) to post-intervention (week 4) and follow-up (week 7). Waitlist control group: Changes from baseline anxiety symptoms (week 1) to pre-intervention (week 4) and post-intervention (week 7). 4-point Likert scale and consisting of 40 questions measuring two types of anxiety - state and trait anxiety.
Usability questionnaire (System usability questionnaire) Waitlist control group: Week 7 (post-intervention). Participants will rate their agreeableness on 10 statements regarding their satisfaction and ease of use of the training components on a 5-point Likert scale. Participants will also answer three qualitative questions regarding their satisfaction and ease of use.
